Something really really minor.

There is no icon for the Simulator menu (Tools -> Simulator). :D :D :D

Excellent work btw.

Yuck!  This is not my idea of a quality library.  The next time you talk
to them, ask them to please include a version string somewhere in their
header files and version their libraries.  Better yet, tell them to
generate this automatically with their build configuration tools.  I
can't believe one of the distros hasn't beat them over the head about
this yet.

Currently there are variables NGSPICE_INCLUDE_PATH and
NGSPICE_LIBRARY_PATH serving this purpose. I will have a look how is it
done in other modules and try to make it coherent.

I thought about this, but the information is not stored anywhere in the
header file, and the library always gets 0.0.0 number (e.g.
libngspice.so.0.0.0), so currently I am out of ideas.

Whoops!  I forgot to mention, version testing is always a good idea.  At
some point it will be an issue and you will have to add support for it.

Hi Orson,

I saw your commit.  Thanks for addressing this issue in a timely mannor.
 I have on minor comment.  FindFoo.cmake files should always have an
option to override the default find location which should take
precedence over the default locations.  Typically this is done with an
environment variable and a definition such as FOO_ROOT.  This allows
developers to use development libraries without having to overwrite
their system default libraries.  I know many of the find modules that
ship with cmake do not do this.  We should not be repeating this bad habit.

Thanks,

Wayne

Hi Wayne,

Sure, both issues are fixed in revisions 7025 & 7027. Again, I had a
chance to test the patches only under Windows and Linux, so their status
for OS X is currently unknown.

Re: [Kicad-developers] Integrated Simulator

[Simon Wells]

When there is a FindNgspice.cmake file it would also allow removal of
#include <../share/ngspice/include/ngspice/sharedspice.h> as it is a
horrible include and should really be added to the -I path

Re: [Kicad-developers] Integrated Simulator

[Wayne Stambaugh]

Congratulations on everyone who made the is happen.  This is a nice
feature for KiCad and hopefully users will find it useful.

There are a few things will need to addressed that I missed when I
initially evaluated the code.

Maybe I missed it but I do not see any indication that the ngspice
headers and libraries are detected during cmake configuration (see
attachment).  This is a major no-no.  All external dependencies must be
found during configuration.  As a developer, there are few things that
make kick a software package to the curb faster than getting 3/4 of way
through a 30+ minute build only have the build fail because there is a
missing dependency header or library.  This should fail during
configuration to inform the developer that there are missing
dependencies.  Please write a FindNgSpice.cmake file.  I know I've said
this in the past but I will reiterate it, if you add a new dependency to
KiCad you *must* add the configuration code to ensure that all of the
required headers and/or libraries can be found before a valid
configuration can be completed.

Also, please update the Documentation/development/compiling.md file with
the added optional ng-spice dependency.  This is the official compiling
document that gets pushed to the kicad website so it needs to be kept up
to date.

Thanks again everyone for your hard work.

Cheers,

Wayne

 Hi,

 As some of you have noticed, we've been working on a "secret" feature
 during the hackathon at CERN. The feature we're talking about is an
 integrated circuit simulator. Currently it features:
 - Seamless integration into schematic editor,
 - AC/Transient/DC sweep simulations,
 - Voltage probing from the schematics,
 - Live tuning of component values.

 A video demonstrating the capabilities of the new simulator is available
 on Tom's YouTube channel [1].

 The code is currently available in the ngspice branch on Tom's GitHub
 [2] for review & testing. It's a big feature, so we didn't want to push
 it immediately to the product branch. We'll greatly appreciate your
 feedback!

 The simulator uses ngspice [3] as the Spice kernel. We'd like to thank
 ngspice developers for providing a DLL interface which made seamless
 integration of ngspice into Kicad possible.

 In order to get started:
 - install ngspice shared library (is not provided by many Linux distros,
 Arch Linux is a known exception, so you might have to compile it from
 the sources with --with-ngshared --enable-xspice options).  Windows
 DLLs, msys2 PKGBUILD & binary packages (to be included soon in
 the official msys2 repo, currently merged to
 https://github.com/Alexpux/MINGW-packages/) & Linux script to build the
 library are available at [4].
 - compile eeschema with -DKICAD_SPICE=ON option,
 - have a look at some examples in demos/simulation directory.

 

Re: [Kicad-developers] Integrated Simulator

[Maciej Sumiński]

I have just merged the ngspice branch. It is still required to enable
KICAD_SPICE switch in cmake in order to use it, so it does not cause
problems on systems without ngspice library installed.

Orson

Hi Jean-Pierre,

I removed the header file intentionally, as it is supposed to be
delivered with (lib)ngspice package. How did you obtain the libngspice
library?

I have just tested a package generated with ngspice mingw64 PKGBUILD [1]
and the new version of get_libngspice_so.sh [2] and they both installed
the header file.

Orson

Hi Orson,

After copying the missing file sharedspice.h from

Hi Orson,

I am trying your spice branch, but I cannot compile your code: a file is 
missing:
in eeschema/sim/ngspice.h:
"#include <../share/ngspice/include/ngspice/sharedspice.h>"
fails (no such file).

Sorry.

Yes, the cursor looks fine, just with your code.
Thanks.

I am using W7 32 bits, wxWidgets 3.1 (and sometimes 3.02)

With initial code, the problem was on both wxWidgets versions.

Hi Orson,

At least on Windows (and perhaps on others OS) the cursor mask looks like it is 
inverted (0 instead
of 1 and 1 instead of 0)
Therefore the probes are not visible on a white background, and are a negative 
shape on a black
background.

Here is a patch to use the right (inverted) mask.
(sorry, the initial mask is not modified, due to my lazyness, the right mask is 
built on the fly).
Not tested on OSX.

Thanks,

Now the script works fine on Linux.
Maybe instead:

it will be good to use:

 I feel bad to provide a bug report on my very first communcation on

 standard SPICE or an LTspice extension, but I tried parameterizing a
 component value, setting a resistor's value to {R} - that sort of

 leads to irrecoverable lockups here.

 Hi,

 As some of you have noticed, we've been working on a "secret" 
feature

 during the hackathon at CERN. The feature we're talking about is an
 integrated circuit simulator. Currently it features:
 - Seamless integration into schematic editor,
 - AC/Transient/DC sweep simulations,
 - Voltage probing from the schematics,
 - Live tuning of component values.

 A video demonstrating the capabilities of the new simulator is 
available

 on Tom's YouTube channel [1].

 The code is currently available in the ngspice branch on Tom's 
GitHub
 [2] for review & testing. It's a big feature, so we didn't want to 
push

 it immediately to the product branch. We'll greatly appreciate your
 feedback!

 The simulator uses ngspice [3] as the Spice kernel. We'd like to 
thank
 ngspice developers for providing a DLL interface which made 
seamless

 integration of ngspice into Kicad possible.

 In order to get started:
 - install ngspice shared library (is not provided by many Linux 
distros,
 Arch Linux is a known exception, so you might have to compile it 
from

 the sources with --with-ngshared --enable-xspice options).  Windows
 DLLs, msys2 PKGBUILD & binary packages (to be included soon in
 the official msys2 repo, currently merged to
 https://github.com/Alexpux/MINGW-packages/) & Linux script to 
build the

 library are available at [4].
 - compile eeschema with -DKICAD_SPICE=ON option,
 - have a look at some examples in demos/simulation directory.

 Happy simulating,
 Tom

Re: [Kicad-developers] Integrated Simulator

[Cirilo Bernardo]

I think your proposal is the best way.  I had to do something similar
many years ago with another scientist's FORTRAN code - in that case
the code either asked for user input or simply called exit() - both of
those being extremely bad behavior for a shared library. From my point
of view your proposed change should be an improvement to the ngspice
code (I hope it doesn't require as much refactoring as the fortran code
I had to deal with).

Hi Johannes,

Thank you for the message. As the current system requirements specify
that KiCad should work with 1024x768 resolution, I am going to resize
the window.

Re: [Kicad-developers] Integrated Simulator

[Maciej Sumiński]

TL;DR: I consider preparing a script that builds patched ngspice DLL to
solve the problem.

The bug stems from the fact that when an error occurs user is expected
to answer whether the simulation should be continued with y/n. As there
is no way we can answer the question when ngspice runs from a shared
library, the simulation hangs.

There is no directive to skip the question. The only way is to run in
batch mode, but it might be done only by running ngspice with -b parameter.

Ideally it should be patched in the ngspice source code (I am going to
propose it to the ngspice devs), but once it is accepted, it will take a
lot of time before the code is included the next release.

What I consider right now, is to modify get_libngspice_so.sh, to make it
multiplatform and add the required patch there. Currently, it should not
be a big deal as the shared library is only delivered by Arch Linux (and
I believe Arch users are able to cope with such problem anyway).

What do you think? Does anyone see a better solution?

Orson

There is a minor issue with the simulator that I came across: the initial
framesize is set to 1280x900 which is too big for my 13" notebook screen
(which is 1280x800).  Usually that is not a problem, but in this case the
window gets placed so that the title and the menu with all the button
controls is off-screen at the top (see attached screenshot).

This is bad as on OSX, without special hotkey knowledge, a user can not
move the window down to get access to the menu bar.  In fact I had to
google for a solution (when holding ALT while resizing the window from
the bottom edge, the window also shrinks symmetrically from the top,
which eventually exposes the title bar).

I see that my screen resolution is probably not the typical size for
serious PCB design and layout work, so I won’t ask for a smaller initial
size.  But perhaps there is the possibility to at least assure that the
title bar of the window will be placed on a visible part of the screen?
Moving and resizing would then be a lot easier for normal users.

Best,
Johannes

 But the simulation and the tune and the probe work.
 It will be nice to have the select of visibility of signals 
(checkbox).

 Because I have the same issue:

 I just copied the dll.

 What is the internal init file?
 And where it should be copied.

 One cannot expect it is in a system folder, especially on windows.

Hi Jean-Pierre,

Thank you for the wxWidgets patch, I have already applied it in my
branch [1]. This week I would like to check & fix the remaining issues
and if nobody raises an objection, I will merge it to the product
branch. It still has to be explicitly enabled, so it should not cause
any problems.

I hope ngspice package will be soon provided by mingw64. The PKGBUILD is
already available in the official repository, so I hope the package will
be there soon. Before it happens, we can still use the PKGBUILD [1].
Mine could have been built with an ancient mingw64 version, so that
might have resulted in a package that does not work with other
installations.

Regards,
Orson

Hi Chris,

Check with a debugger if it freezes inside ngspice yes_or_no() function
which prompts the user on the console whether to continue or not. It
seems you have an error in your circuit. NgSPICE DLL does not have all
communication channels redirected to the callback functions, some of
them include reporting problems with parametrizable components.

If this is the case, we should contact NGSpice team to fix this (or send
them a patch ;-)

Tom

PS. Could you upload the circuit that triggers the freeze?

 Hi,

 As some of you have noticed, we've been working on a "secret" feature
 during the hackathon at CERN. The feature we're talking about is an
 integrated circuit simulator. Currently it features:
 - Seamless integration into schematic editor,
 - AC/Transient/DC sweep simulations,
 - Voltage probing from the schematics,
 - Live tuning of component values.

 A video demonstrating the capabilities of the new simulator is available
 on Tom's YouTube channel [1].

 The code is currently available in the ngspice branch on Tom's GitHub
 [2] for review & testing. It's a big feature, so we didn't want to push
 it immediately to the product branch. We'll greatly appreciate your
 feedback!

 The simulator uses ngspice [3] as the Spice kernel. We'd like to thank
 ngspice developers for providing a DLL interface which made seamless
 integration of ngspice into Kicad possible.

 In order to get started:
 - install ngspice shared library (is not provided by many Linux distros,
 Arch Linux is a known exception, so you might have to compile it from
 the sources with --with-ngshared --enable-xspice options).  Windows
 DLLs, msys2 PKGBUILD & binary packages (to be included soon in
 the official msys2 repo, currently merged to
 https://github.com/Alexpux/MINGW-packages/) & Linux script to build the
 library are available at [4].
 - compile eeschema with -DKICAD_SPICE=ON option,
 - have a look at some examples in demos/simulation directory.

 Happy simulating,
 Tom

Re: [Kicad-developers] Integrated Simulator

[Eldar Khayrullin]

Hello guys. I think this news should be announced in 
http://kicad-pcb.org/post/ to promote the interest.

 This is the problem, ngspice can't find its internal init file. 
Did you

 install it in your system or just copied the DLL?

 Tom



 Because I have the same issue:

 I just copied the dll.

 What is the internal init file?
 And where it should be copied.

 One cannot expect it is in a system folder, especially on windows.



 Hi Tom,

 After more tests:

 In all cases I have the message:
 Note: can't find init file.

 However:
 * sallen_key does not work at all (as said previously)
 * laser_driver runs but gives the message:
 doAnalyses: Too many iterations without convergence
 run simulation(s) aborted
 * rectifier works!


 Hi JP,

 You need the init files and XSPICE extensions. I'll provide an 
updated

 Windows package.

 Tom



Hi Tom and Orson,

After a few trials, I fixed my issues:
* sallen_key.sch demo has a bug: the text ".include diodes.lib" 
should be ".include 8051.lib".

  Of course, this is obvious, bot not easy to find at a first glance.
* I rebuilt libngspice-0.dll on my msys2 install, just copied this 
dll in kicad/bin dir (instead of
Orson'one) and I do not have the issue about init files (perhaps it 
is built with different options).

This is the problem, ngspice can't find its internal init file. Did

install it in your system or just copied the DLL?

Re: [Kicad-developers] Integrated Simulator

[Tom Andrews]

Hi guys,

Thanks very much for adding this feature for a start, definitely something
I've been wishing for.

Run into an issue off the bat;
Used the script to download/compile the shared lib, and compiled eeschema
with -DKICAD_SPICE=ON, all good.
Loaded up eeschema and opened up sallen_key.sch, opened the simulation
window and set setting to transient with 1n step and 1s finish time,
clicked OK and pressed Run/Stop Simulation, it said no circuits loaded, I
stopped and restart the simulation and the program segfaulted, with this
error in GDB.
(I'm running LMDE 64 bit, kernel 3.16.0-4-amd64)

Yup, ngspice has XSPICE support compiled in. Forcing C locale changes
the behavior slightly but doesn't fix it:

With default locale (en_US.utf8), a simple circuit consisting of a
voltage source V=12 and a resistor {R} with the parameter left
unspecified freezes kicad completely (can only be quit by SIGTERM). With
C locale, this doesn't seem to cause a freeze, but after attempting
to specify that parameter by adding ".param R 12", *then* it freezes.

Hi JP,

You need the init files and XSPICE extensions. I'll provide an updated
Windows package.

Thank you CERN for contributing this excellent addition to KiCad.
Needless to say that I was shocked at how far along the simulator was
when I arrived at CERN since I had no idea they were even working on
simulation.  It moves KiCad one step closer to world domination! ;)

Hi Tom,

After more tests:

In all cases I have the message:
Note: can't find init file.

However:
* sallen_key does not work at all (as said previously)
* laser_driver runs but gives the message:

Because I have the same issue:

I just copied the dll.

What is the internal init file?
And where it should be copied.

One cannot expect it is in a system folder, especially on windows.

Hi, tom,

First, great work. Thanks to all CERN guys.

On W7 32 bits I have a similar issue (using sallen_key.sch).
Here is a copy of the message panel:

Note: can't find init file.
**
** ngspice-26 shared library
** Creation Date: Tue Jul 12 14:24:11 CEST 2016
**
Error: .include filename missing
Error: ngspice.dll cannot recover and awaits to be detached
Error: there aren't any circuits loaded.

The libngspice-0.dll comes from 
https://orson.net.pl/pub/libngspice/windows/i686/.
I have just copied in in the kicad/bin folder.

Are there some requirements on Windows I am not aware of?

I had also a compil issue due to the fact mathplot is a bit old.
Attached my (small) fixes to compile it on wxWidgets 3.1 on W7 32 bits (without 
this fix, it does
not compile)

Hi Eldar,

Compile ngspice with --enable-xspice option.

Hi Chris,

Two quick questions:
- Do you have NGspice compiled with XSPICE support?
- Could you run eeschema with forced "C" locale?

Hi,

As some of you have noticed, we've been working on a "secret" feature
during the hackathon at CERN. The feature we're talking about is an
integrated circuit simulator. Currently it features:
- Seamless integration into schematic editor,
- AC/Transient/DC sweep simulations,
- Voltage probing from the schematics,
- Live tuning of component values.

A video demonstrating the capabilities of the new simulator is 
available

on Tom's YouTube channel [1].

The code is currently available in the ngspice branch on Tom's GitHub
[2] for review & testing. It's a big feature, so we didn't want to 
push

it immediately to the product branch. We'll greatly appreciate your
feedback!

The simulator uses ngspice [3] as the Spice kernel. We'd like to thank
ngspice developers for providing a DLL interface which made seamless
integration of ngspice into Kicad possible.

In order to get started:
- install ngspice shared library (is not provided by many Linux 
distros,

Arch Linux is a known exception, so you might have to compile it from
the sources with --with-ngshared --enable-xspice options).  Windows
DLLs, msys2 PKGBUILD & binary packages (to be included soon in
the official msys2 repo, currently merged to
https://github.com/Alexpux/MINGW-packages/) & Linux script to build 
the

library are available at [4].
- compile eeschema with -DKICAD_SPICE=ON option,
- have a look at some examples in demos/simulation directory.

Happy simulating,
Tom

Really, really nice! I made it do a thing! https://misc.c4757p.com/kicad_sim.png

I feel bad to provide a bug report on my very first communcation on
this, but... found one: not sure if this sort of thing is actually
standard SPICE or an LTspice extension, but I tried parameterizing a
component value, setting a resistor's value to {R} - that sort of thing
leads to irrecoverable lockups here.

Good work CERN hackathons!
I know some people that are looking for this specific feature to start using 
KiCad. I am spreading the word...

You know this, but for the list: I think once the single schematics
object is in place for eeschema, integrating python scripting with the
simulation would be a really nice feature.

Cheers,

Javier
